Benefits of technology

The apparatus provides a highly reliable processing result by capturing and analyzing endothelial cell images at multiple positions, improving the accuracy of endothelial cell analysis, especially in cases where the number of detectable cells is low, such as in diseased eyes.

Problems solved by technology

However, the conventional apparatus displays only a single endothelial cell image and the analysis result for the endothelial cell image on a monitor.

embodiment

[0074]Hereinafter, an exemplary apparatus according to this embodiment will be described with reference to the accompanying drawings. FIG. 1 is a side view schematically illustrating a configuration of a corneal endothelial cell photographing apparatus according to this embodiment.

[0075]This apparatus 100 is what is called a stationary apparatus. This apparatus 100 includes a base 1, a head support unit 2 mounted on the base 1, a movable table 3 movably disposed on the base 1, and a photographing unit (the main unit) 4 movably disposed with respect to the movable table 3. The photographing unit 4 includes a monitor 95. The movable table 3 can move in the X- and Z-directions on the base 1 by operation of a joystick 5.

[0076]The photographing unit 4 includes the monitor 95. The movable table 3 can move in the X- and Z-directions on the base 1 by operation of the joystick 5. That is, the photographing unit 4 is moved, by a XYZ driving unit 6 disposed in the movable table 3, in a right-a...

Abstract

A corneal endothelial cell photographing apparatus for photographing an endothelial cell in the cornea of the examinee's eye includes an optical system, an image processor, and a display controller. The optical system includes an illuminating optical system for irradiating the cornea with illuminating light, and a light receiving optical system including a light detector and configured to receive reflected light from the cornea including the endothelial cell. The image processor analyzes each of endothelial cell images photographed at different positions on the cornea, and acquires an integrated analysis result by integrating the result of analysis of each of the endothelial cell images. The display controller displays the endothelial cell images simultaneously on a monitor with reference to an endothelial cell image photographed at a central portion of the cornea, and displays the integrated analysis result on the same screen as for the endothelial cell images.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based on Japanese Patent Application No. 2012-156474 filed with the Japan Patent Office on Jul. 12, 2012, the entire content of which is hereby incorporated by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to a corneal endothelial cell photographing apparatus.[0004]2. Related Art[0005]A corneal endothelial cell photographing apparatus for photographing an endothelial cell image of the eye of an examinee (hereinafter also referred to as “examinee's eye”) is known (see, for example, JP-A-2011-245184). The apparatus irradiates the cornea of the examinee's eye with illuminating light, and receives reflected light from the endothelial cells in the cornea, thus photographing an endothelial cell image.[0006]The apparatus analyzes the obtained endothelial cell image and outputs an analysis result including the number of endothelial cells and their density, for example. However, the conventiona...
